Aluminium Tube OD Finishing: Important Ra 0.1 Guidance

Summary for aluminium tube od finishing Discussion

Aluminium tube OD finishing is the core question here: Vishal Pimple asks how to achieve an OD surface finish of Ra 0.1 on an aluminium tube sized ID 28 x OD 32 x L250 mm. The only answer in the thread comes from an unnamed responder, who first notes that the dimensions are assumed to be in millimeters and then says the key missing factor is production volume. In other words, the best finishing method cannot be confirmed from size alone; the appropriate process will depend on how many parts are being processed. No specific finishing technique is recommended in the excerpt, so the discussion remains a request for more information before a practical method can be chosen.
